45. Although there is no theoretical lower limit to the film thickness for propagating modes in the symmetric waveguide, there is certainly a practical limit due to the fact that the propagating mode has evanescent tails that extend into the substrate and cover, so that as the film gets thinner and thinner, most of the propagating wave is sampling the substrate and cover rather than the film, and the total scattering signal becomes due primarily to scattering in the substrate and cover rather than the film. The thinner the film, the greater the contribution to the scattering from the substrate and cover, and thus the lower the signal-to-noise ratio.
